To all whom it may concern:

Be it known that ,.R1ox-1ARD PAYTON, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Flows, of which the following isa specification, reference being had therein to the accompanying drawing. r

This invention relates to improvements in plow bottoms and isvl especially adapted for use in steam plows in which a number of bottoms are secured to the same tractor frame,

The object of the invention is to provide a plow bottom in which the point or share may be readily and quicklyA detached from or attached to the other parts of the plow bottom.

In the accompanying drawings T have shown one embodiment of my invention. It will be understood, however, that various changes may be made in the arrangement of parts and in structural details within the scope of my invention.

Of the drawings-Figure 1 is a bottom perspective view of a plow embodying my invention. Fig. 2 is a perspective view taken from the front. Fig. 3 is a bottom view of the detachable share detached from the other parts of the plow bottom. Fig. al is a perspective view of the share taken from the rear. Fig. 5 is a cross sectional view of the low taken through the connection for the detachable share.

Referring to the drawings, 1 represents the plow point or share; 2 the mold-board; 3 the land-side; and l the frog to which the other parts are attached.

5 isa standard to which the frog is attached and by means of which the plow body is moved.

The frog is bent and forged into suitable shape, and to one part of it is attached the mold-board by means of bolts or rivets. To the other part is rigidly secured the landside 3, also by suitable bolts or rivets. The mold-board, the frog and the land-side will, for the sake of convenience, be designated as the plow body.,

The plow share 1 is formed with one part 6 adapted to aline with the mold-board, and part and adapted to aline 'with the land-side 3. The parts 6 and 7 each engagev with and are supported by the forward end of the frog. The forward side of the share is ground to a sharp edge, and it is for the purpose of resharpening this edge from time to time-that the share is made detachable.

It will be noted by a reference to Figs. 2 and 3 Athat the part of the share 1 which is 1n alinement with the land-side 3 is extended backward to a point beneath the edge of the mold-board 2, a shortnledge 8 being thus formed which is adapted to engage with the underside of the mold-board. This ledge aids in holding the parts in alinement, and

its purpose will be more fully set forth hereafter. y

9 represents a tensionbolt, or equivalent device, which is connectedby a rivet, or otherwise, at its forward end to the under side of the moldboard section of the plow share. This bolt extends at a lateral acute angle to the rear edge of the moldboard section of the share .and in such a direction' that tension on the bolt will tend to slide the share relative to the mold-board'to maintain the part 7 in firm engagement with the side of the frog li. The bolt 9 also lies at a downward acute angle to the plane of the\ share. Tension on the bolt, therefore, also tends to hold the part 6 of the share in firm engagement, not only with the edge of the mold-board, but also with the upper surface of the frog 4;. From the upper or main body part of the frog i there is struck down a depending integral casing or housing 10 which forms a socket forthe bolt 9, the rear end of which extends through the open rear end ofthe socket.- The bolt is provided preferably with a washer 11 and a nut 12 by means of which the bolt may be tensioned and the share thereby drawn into and maintained in proper position.

lt willvbe noted that the ledge 8l in cooperation with the frog l positively maintains the part of the share adjacent the landside in proper alin'ement. The bolt 9 holds the other side. of 'the share in close contact with the frog and in alinement with the mold-board, and also prevents any lateral displacement of the share relative to the plow body. l

When it is desired to remove the share for the purpose of sharpening or making other repairs, it is only necessary to remove the nut l2 and the washer 11 thus leaving the share entirely free.
